Boys leave elite school over sex acts

Three 14-year-old boys from Cranbrook have agreed to leave the elite Sydney private school after a sexual incident involving a 14-year-old girl.

The incident is said to have taken place at a teen "gathering" during the current school holidays on the grounds of Bronte Public School, in Sydney's eastern suburbs, after the girl sent a text message to one boy and arranged to meet him, Fairfax Media reports.

The girl reportedly had consensual sex with one Year 8 boy but two other boys who were present then allegedly engaged in sex acts with her as well.

Marijuana or alcohol may have been involved.

Cranbrook principal Nicholas Sampson said the incident came to the school's attention and the school had discussions with the families of those involved.

"As a result of those discussions, the boys are no longer part of the school community," he said.

It is the second such incident involving young Cranbrook boys with young girls in recent months.

In late September, at the end of term 3, two Year 9 boys, aged 15, are alleged to have had sex with a very drunk Year 8 girl at a party in Sydney's east while a third boy allegedly filmed it on his smartphone.

The school proposed referring that incident to the police but the girl later withdrew her version of events and no charges have been laid.

On Tuesday night, Mr Sampson wrote to parents alluding to the events.

"Adolescence has always been a time when risks are taken as the world of adulthood is explored: it does not, however, license young people to suspend traditional morality or disregard either common sense or the law," he said.

"As a boys' school, Cranbrook has a particular duty to encourage and enable its students to behave with courtesy and respect, particularly towards girls in their peer group."
